4 Claims.

This invention relates to a method and means for applying a conditioning liquid such as lubricants, dyes, tints, hydroscopic agents, and the like to textile stocks and particularly the application of oil or dyestuff or any conditioning agent to raw textile stocks or textile blends in the course of manufacture in the normal sequence of operations incident to the finished product.

According to my invention, the stock is treated while in lap or mass form and is subjected to the conditioning liquid b having the liquid deposited on the moving fibers in the form of fine droplets by means which are oscillated and vibration iniparted thereto so as to divide the drops into small globules, and depositing the same onto the travelling mass of fibers as it advances.

I accomplish the application of the liquid to the moving textile fibers by conducting the liquid to a reservoir pipe disposed transversely of the travelling mass of fibers and feed the conditioning liquid through a plurality of nozzles extending from said reservoir or openings in the top portion of the reservoir and impart oscillation and vibration to said reservoir pipe so as to shake the drops from the nozzles or projections and to break them up into many fine droplets to cast them onto the fibers travelling thereby.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying. drawings, in which:

Figure 2 is a transverse sectional View taken along the line 2-2 in Figure 1;

Figure 3 is a vertical sectional View taken along the line 33 in Figure 2;

Figure 4 is a top plan view taken along the line 4-4 in Figure 2;

Figure 6 is a view similar to Figure 2, but showing another form of the reservoir pipe;

Figure 7 is a cross-sectional view taken along the line ll in Figure 5;

Figure 8 is a longitudinal sectional view of the reservoir pipe;

Figure 9 is an elevation of a short section ofa modified form of the reservoir pipe;

Figure 10 is a longitudinal section through the form of reservoir pipe shown in Figure 9.

In the conventional picker 9, illustrated in the drawings, the stock I0 is supported on a conveyor II and by it is continuously advanced towards a beater chamber l2 in which a conventional beater, not shown, is disposed for engaging the stock and beating the same.

It will be understood that the term lap is used herein, not in its limited sense to denote only the finished lap, but to include also the sheet, mass or bat form at Various points in its course t and through the picking and opening machinery.

Mounted on the upper frame members l4 and i5 of the picker are standards [6 and I1 having bearings l8 and it there-on in which is mounted for oscillation a pipe 20. This pipe 20 has suitable fins 2! on each side thereof which are adapted to work in suitable grooves in bearing 18, for example to prevent turning movement of the pipe. The pipe 20 has rising from the top surface thereof a plurality of inverted U-shaped nozzle members 25 which project upwardly, then lat erally, and then downwardly, and have a restricted nozzle portion 25. In Figure 1, these pipes 25 are shown as one piece, and in this form would be welded or brazed to the main pipe 26 whereas in Figure 3, for example, instead of having the inverted U-shapedpipes 25, there is provided a vertically disposed reservoir pipe 30 having its lower end threadably secured in the pipe 20, and having its upper end closed by a cap 3| and having threadably secured in one of its side walls an L-shaped pipe 32 whose lower end is restricted as at 2B for allowing the oil, dye, or other conditioning fluid to drip therefrom in the form of droplets.

The ends of the pipe 2|] are closed by suitable cap members 35 and 36 and between the bearing l9 and cap 36 is a compression spring 3'! which normally tends to move the pipe to the right in Figure 2 to where the cap 35 will rest against bearing l8. This pipe 20 is adapted to be oscillated by means of an electric motor it being mounted on the frame and adapted to be driven by any suitable source of electric current through Wires 4| and 42. This electric motor has a motor shaft 43 which enters a gear reduction box 44 and from gear reduction box 44 a shaft 45 is provided which has a cam 46' on its upper end adapted to engage the cap 36 and to impart oscillation to the pipe 20 by pushing the pipe all the way to the left in Figur 2 until the high point 50 of the cam 46 is reached, at which time, the compression spring 31 will quickly move the pipe 20 to the right in Figure 2 until its cap 35 engages bearing l8 which will suddenly stop the pipe 20 and cause any drops emanating from the restricted portions 25 to be broken up into fine droplets and cast upon the travelling. lap of cotton l0. These vibrations can be as many per minute as desired in order to properly break up the drops of conditioning liquid or dye into droplets.

Leading from and connected to pipe 20 is a flexible tube 5! which is connected to a flow control and manually operated valve 52, and the other side of the valve 52 is connected to a solenoid or other shut-off valve 53 whose wires 54 and 55 are connected to the same electric current as electric motor 40 or to an independent source as drives the textile machinery.

The oscillating motion may be obtained by independent motor or a mechanism synchronized with the textile machine movements so that the flow can be started and stopped by valve 53 when the machine starts or stops.

Leading from valve 53 is a pipe 56 which is connected to an elevated tank 51, which serves as a source of supply or, if desired, pipe 56 may be supplied by a force feed as for instance a pump leading to a suitable source of supply.

The flow control valve '52 can be adjusted to allow the desired amount of liquid to fiow into reservoir pipe 20. The reservoir pipe 20 is full at all times and rises into pipes 25 and to nozzles, then drops down the vertical portion of the pipes 25 and out through opening 26. On account of this feature, when the valve 53 is closed, or the flow control valve 52 should be closed, since there is no appreciable amount of liquid present in the pipe 5!, it is thus seen that the flow of liquid through the nozzles 26 will stop almost immediately upon stoppage of the textile machine, and thus no great amount of liquid will be deposited onto the mass of fibers I0.

If desired, any liquid can be applied with satisfactory results by operating the pipe 20 while stationary, that is, allowing it to stand in normal position, but I believe that better results are obtained by vibrating the apparatus and giving frequent jars thereto to detach the drops of liquid from the nozzles thus breaking them into finer droplets than if the liquid is allowed to drop onto the lap of moving fibers l without vibrations for the reason that the drops of conditioning liquid are evenly distributed through the mass by mechanical contact after it passes through the mechanic-a1 beating chamber [2, because there the fibers are disintegrated and formed into a new combination and those fibers which have a greater amount of fluid thereon impart the liquid to other fibers with a lesser amount thereon, and thus the fluids are evenly distributed as it is beaten immediately after being deposited onto the moving web l0.

In Figures 6-10 inclusive, there is shown a modified form of the reservoir pipe designated as 29a. In Figure 6, much of the structure is similar to the structure shown in Figure 2, and like reference characters will apply. However, in this modified form of the invention instead of having the upwardly, laterally, and downwardly extendin nozzle pipes 25, I have shown the reservoir pipe 20a with a plurality of circumierential grooves 60 and coinciding with the top portion of each of these grooves 69 and at the uppermost part of the reservoir pipe 20a, there is a perforation or hole 6! and in the bottom of the reservoir pipe 20a, there is secured a solid plug 62 which is pointed at its lower end so that the treating liquid will flow out of the openings 6| and be directed downwardly by the circumierential grooves 60 onto the plugs or teats 62 which being pointed, at their lower ends causes the drops to collect on the points and to be more easily shaken therefrom. While these plugs 62 are shown threadably mounted in the pipe 20a, and having a squared portion 63, to be engaged by a wrench, it is evident that they could be welded onto the pipe 20a or cast integral therewith as evidenced by the teats 64 as shown in Figures 9 and 10. Such pipe 29a would also I have circumferential grooves 60 and openings 6| as previously described.

In the drawings and specification, there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of th invention being defined in the claims.
